<pre>commit 0d028f8fd07f0a4b46c9e4659eb3caf93a69ac11

igt/gem_userptr_blits: Errors from gup are permanent
After triggering an error (such as trying to use userptr on a GTT
mmaping), we store the EFAULT on the object permanently. So to test the
error, we must sacrifice the object and recreate the userptr handle.
We restrict the error to just one of the overlapping userptr handles to
check the object independence.
